RS232.C was written to provide all of the basic functionality needed to employ serial I/O in any application written with Borland C language compilers. Some features are: 1. Ease of use. No assembly language or library files are used and a simple "#include" statement is all that is required to access all of the functions provided. 2. Both input and output are buffered and INTERRUPT driven for efficiency. 3. Serial ports 1 - 4 are supported on PC, AT and PS/2 compatibles.Chained INTERRUPTs used on port 3 and 4 are allowed for so as not to interfere with devices such as a mouse or printer. Transmission speeds of 110 to 115200 baud are available. 4. Detection and utilization of hardware buffered UARTs (NS16550AF etc.) found in some machines is automatic. 5. INTERRUPT driven hardware and XON/XOFF flow control is provided for. 6. All source code is included. RS232.C can be used with all memory models.

The sample software includes, common library, peripheral APIs, and test modules for the APIs. The common library include startup file, standard definition and header files, processor specific setup module, generic INTERRUPT related APIs, timer routine, and scatter loading file. The peripheral directories include, GPIO, PWM, Real-time clock, timer, SPI, I2C, Watchdog timer, UART, external INTERRUPT, etc.

DESCRIPTION =========== This example project shows how to use the IAR Embedded Workbench for ARM to develop code for the Atmel AT91SAM9261 evaluation boards. It shows basic use of parallel I/O, timer and the INTERRUPT controller. It starts by showing different patterns on the LED s separated by half second. COMPATIBILITY ============= The project is compatible with the AT91SAM9261-EK board.

The ISD51_Demo project for the MSC1200 shows how to use the ISD51 In-System-Debugger with flash breakpoints or hardware breakpoints. By default, it is configured for flash breakpoints which allow you to set real-time breakpoints in your software. Using Flash breakpoints has also the benefit that no special handing for the shared INTERRUPT vector is required, since the hardware break registers of the MSC1200 are not used at all.

Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer count dependent INTERRUPT generation. As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface. Very simple, very small.

1. This BSP can support 2443EVT0 board. If you want to use EVT0 BSP, set followings. In smdk2443\smdk2443.bat file set BSP_EVT1=1 -> set BSP_EVT1= In smdk2443\src\inc\bsp_cfg.h file #define EVT1 -> #define EVT0 2. Default system tick mode is changed. The value is fixed tick. Fixed tick means that tick INTERRUPT is occurred every 1ms. Variable tick means that timer INTERRUPT period is changed when power mode is in idle. For changing to variable tick In smdk2443\src\inc\bsp_cfg.h file #define FIXEDTICK -> #define VARTICK In smdk2443\src\Common\Timer\Sources file SOURCES= timer_fixedtick.c watchdog.c -> SOURCES= timer_vartick.c watchdog.c
